The dossier says they're passive to humans and only attack little fish THIS IS NOT TRUE THEY WILL EAT YOU AND THEY TEAM UP WITH ELECTROPHORUS TO KNOCK OUT YOUR MOUNT AND SHARE IN THE FEAST AFTERWARDS!!

Plesiosaurs are the quetzals of the ocean change my mind

My trusty sarcosuchus made knocking my plesi exceedingly simple, for three reasons. The sarco is fast, it ascends quickly, and you can shoot from its back. Once I separated my plesiosaur from her friend and killed it, the procedure was simple. When the plesi reaches a certain height it begins to flee. I dragged her up then filled her with tranqs until she aggro'd again. Repeat process until unconscious. Simple with sarco.

Has anyone thought to put auto turrets on its platform saddle. You don’t need megalodon guardians anymore.

It's like a fish but bigger

Taming one is not too difficult. A high level won’t take too many tranq to knock out. When it’s knocked out, feeding it a soothing balm will allow u to tame it quickly, even with regular raw meat. Don’t forget to separate the plesiosaur u want from others in the area. Good luck!
(Like if this helps)

There is a glitch at the redwood on the center, where plesiosaurs will spawn really near the coast and whole groups of 2 or 3 are glitched in the water, meaning you can knock out multiple plesiosaurs at the time.

Build a house on the platform.. then you have underwater home!!!!!!!!

The trick is to argo one, have him chase you into an underwater cave where he will not be able to fit through the door but his long neck and head does. when you do this he will not de-agro, you can then get a clear shot from the cave with a bow and tranq arrows

These guys are great and super fast and also very strong. Warning when your gonna go tame these guys bring a sarco or an icthy , they also spawn In 2,s or 3,s so be careful because these guys do a crap ton of damage .

They can't fit through the resource caves' entrances. Just lure it into one and pull out your crossbow/harpoon gun for the knock out. Just be aware of any nearby megalodons, as they can fit into the cave easily and ruin your swimming session.

You're gonna need about three fiddy, then this beast will let you go.

The weakness of plesiosaur is the depth limit. Use it to tame it.this also work for mosasaurs. Scuba tank and flipper recommended

Thing can fly, is this a glitch or what?

I manged to get into a river because these dudes can levitate and don't take damage so the poor bobs saw the unspeakable as the loch Ness monster ate them with this long butiful neck of terror.

I was taming a mosa with my friend and 7 of these of the these underwater giraffe cat eels came at me like the Texas chainsaw massacre guy just as scary too. What I’m saying bring and army of megladons and mantas

This has to be the most terrifying creature on ark. I've tamed one and it still makes me piss my pants when i see it.

If you pump their speed and stam, you have a underwater transportation rocket

Put a grill on platform. Farm other plesiosaur for prime meat. Cook underwater

Plesiosaurs will team up and try to kill you
